This compact amplifier is a great way to power a pair of speakers without the bulk of a full size hi-fi receiver. It provides 2x15W RMS output power - enough to power a pair of small ceiling or bookshelf speakers. 6.35mm and 3.5mm inputs are provided for direct connection to a microphone or MP3 player. It could even be hooked up to a wireless Bluetooth adaptor (such as A 1102) for audio streaming from your smartphone or tablet. Includes power supply.
